Abstract:
Liquid crystal display (LCD) touch screens integrate touch sensing elements with display circuitry and may include in-plane-switching (IPS) LCDs. A method of operating the integrated touch sensing elements with the display circuitry includes dividing touch-sensing circuitry of the touch screen into a plurality of drive segments, each drive segment overlapping one or more display rows; updating the display at a predetermined refresh rate; stimulating the plurality of drive segments at a predetermined scan rate; and changing the sequence of stimulating the plurality of drive segments as required to prevent simultaneously stimulating a drive segment that overlaps a display row currently being updated.
